"Yesterday there was a car that was lost in one of the fires up on the Dublin/Wicklow border.

"We would appeal to people not to come and look at these. The wind can change directiin extremely quickly. Do not come and look at them.

"They can burn down towards the roadways, you become disorientated if you get caught in the smoke. We're asking people to just stay away."

Earlier: Restrictions in place as demand for water exceeds supply by 5m litres in Dublin

Latest 12.46pm: People in Dublin could be facing water outages and restrictions as the demand in Dublin is now more than can be supplied.

Demand is now at 615 million litres but the maximum that can be produced is 610 million.

Around 10,000 people across the country are currently having their water restricted at off-peak times but this could increase further.

Kate Gannon from Irish Water says the situation is being closely monitored.

"Well, our operational teams are meeting on the ground at the moment, and they are looking at all available options such as reconfiguring the network and looking at different ways to supply people," she said.

"However, with the existing excessive demand, we are looking at a significant increase in the risk of restrictions and outages in the coming days unless things change."

The high temperatures continue to cause fires as thousands of acres of land have been damaged by fires in the past few days.

Parts of Leinster are officially in drought, while two areas in Connacht are having to rely on a backup supply.

The drought is causing significant concern for farmers who are worried they won't be able to save enough fodder for next winter as they try to catch up with the wet spring this year.

Seamus Granahan from Irish Water is asking customers to reduce usage and conserve water.

"Rural areas and urban areas, both have increased demand," he said.

"We appreciate that farmers have to provide water for their livestock, cattle and dairy herds so demand has gone up significantly and as a result of that demand we are in a critical situation."

Irish Water is being urged to prosecute homeowners who do not fix leaks on their properties.

Green Party Councillor Ciaran Cuffe says the heatwave is making it more important than ever to deter people from wasting supplies.

"I had a look at the legislation and the Water Services Act 2007 says Irish Water can prosecute if somebody is just allowing water to be wastefully leaked so I think Irish Water need to up their game a little bit," he said.

The high humidity levels are also creating the ideal condition for forest fires.

There are warnings of gorse fire after a family was rescued from the Dublin Mountains last night.

Firefighters have had to tackle a number of gorse fires over the past few days and Mick Power from Coillte has warned that the smallest spark can start a fire.

"We're appealing to people today to be extremely careful during this hot spell," he said.
